Technical field
The present invention relates to alleviate the method for the high frequency fatigue of the turbosupercharger that is contained on the internal-combustion engine, specifically say, the present invention alleviates the high frequency fatigue of turbocharger turbine blade.
Background technique
Turbosupercharger is that people are being higher than under the pressure of atmosphere (boost pressure) the air fed device of the inlet of internal-combustion engine being used for of knowing.Common turbosupercharger mainly is the exhaust-driven turbine wheel that has in the rotating shaft that is installed in the turbine cylinder, the rotation of this turbine wheel is rotated the compressor impeller on the other end that is positioned at compressor housings that is installed in above-mentioned rotating shaft, thereby this compressor impeller carries air pressurized to improve the power of motor to the inlet manifold of motor.
Above-mentioned turbine wheel is owing to the tired limiting factor in turbocharger operation life-span often that lost efficacy.There is various reason to cause the fatigue of turbine blade, one of this reason is turbine wheel blade generation harmonic vibration, if turbine especially turns round above-mentioned blade harmonic vibration just may take place, be called high frequency fatigue under full load/maximum (top) speed condition under constant speed.The impeller blade of turbocharger air compressor also bears the effect of high frequency fatigue on less degree.High frequency fatigue depends on the work cycle of the motor that turbosupercharger is housed to a certain extent for the influence of the operating life of turbine wheel.Above-mentioned high frequency fatigue is especially closely bound up for the turbosupercharger of industrial use, and turbosupercharged engine will long-term operation under constant maximum (top) speed in this purposes.
The aspect content

Will be appreciated that more favorable characteristics of the present invention from following explanation people.
Description of drawings
Only in conjunction with the drawings example illustrates the present invention below, in the accompanying drawing:
Fig. 1 illustrates the example of the fuel oil figure of internal-combustion engine;
Fig. 2 simply illustrates a kind of control system that alleviates high frequency fatigue according to the present invention; With
Fig. 3 simply illustrates the another kind of control system that alleviates high frequency fatigue according to the present invention.
Embodiment
The running of Modern Internal-Combustion Engine is controlled by a kind of Motronic control maps control gear that often is called ECU (electronic controller) usually.Above-mentioned ECU receives from the various performances of relevant motor of each detector and the data of work requirements, thus and the running of control motor.If motor is equipped with turbosupercharger, ECU can additionally receive the signal that shows the turbosupercharger operating mode, and also can use some direct controls between the operational period of turbosupercharger.
Conventional ECU has one and is used to control based on the data " look-up table " of a series of data points of measuring the by experiment processor of the engine performance of data " figure " in other words, according to above-mentioned data " look-up table " in other words data " figure " can determine specific job requirement from various location parameters.Fuel oil figure is exactly a kind of above-mentioned datagram, and Fig. 1 illustrates the example of this fuel oil figure.Fuel oil illustrates the relation between fuel oil requirement (or consumption) and engine speed and the torque request.By data Ax, Bx, the different engine speed/torque-demand state shown in the Cx...... etc. marks various fuel oil value in the drawings.For the engine speed/torque-demand that can not draw clearly, can draw suitable fuel oil value by interpolation according to the mapping value.
The electronic controller of above-mentioned control engine fuel can very accurately be controlled the whole speed range of starting, thereby also very accurately controls the secondary speed of turbosupercharger.The present invention assert that above-mentioned accurate control can aggravate the problem of high frequency fatigue, in other words, if engine operating condition requires constant rotating speed, ECU will provide this validity very high constant rotational speed, in like manner, if the work cycle of motor requires to start to turn round down at specific rotating speed of target (for example Zui Da rotating speed and load) continually, the work of ECU will guarantee all reaching identical rotating speed of target in each running so.
Basic principle of the present invention be will be a kind of disturbance introduce the running speed that deliberately changes turbosupercharger in the operation of turbosupercharged engine (under the operating condition of tangible high frequency fatigue can appear in expectation, doing so at least), thereby reduce of the influence of high frequency fatigue to each blade.The present invention achieves the above object by the disturbance of introducing engine oil.
Fig. 2 simply illustrates the first embodiment of the present invention.To show that the signal that engine speed and load (torque) require is input among the ECU of motor, this ECU determines to satisfy the required fuel feeding value F of job requirements according to the engine fuel Fig. 2 that is programmed in advance in it, and sends suitable fuel supply signal to oil supply system 3.According to the present invention, send the disturbing signal E that regularly changes to oil supply system 3 to change fuel delivery, like this, to the fuel delivery of motor be F-E (wherein E can be on the occasion of or negative value, and can be from the occasion of becoming negative value).Above-mentioned disturbing signal can be a kind of signal of random change, or a kind of periodic signal of rule for example sine wave or square wave signal etc.Suitable frequency is about 0.1 second usually～and 10 seconds.
Therefore, above-mentioned disturbing signal can prevent that motor from turning round the long time cycle under a kind of constant rotational speed.The resonant frequency of any single turbine blade of turbosupercharger will have high Q value, so only need rotational velocity to have deviation (deviation that is equivalent to several hertz of levels) a little just can leave the resonant frequency of any particular vane, therefore, only need engine speed (comprising turbo charger speed) to have very little variation just can guarantee that significant resonance does not take place any particular vane.Should be kept in mind that different blades will have different resonant frequencies.Therefore,, have one or more blade generation resonance, but the vibration and the fatigue thereof of any particular vane will reduce obviously in any given moment.
Can guarantee that preferably above-mentioned disturbance can not damage the performance of motor.In fact, 3% the disturbed value that is no more than normal regulation fuel oil value F can obviously not influence engine performance, significantly alleviates high frequency fatigue but can make turbo charger speed produce enough variations.This has just obtained the high Q value of the resonant frequency of each turbine blade.
Though show the situation that disturbing signal is transferred to oil-fired system as mentioned above and at Fig. 2,, essential disturbed value is incorporated into the fuel oil value of supplying with oil-fired system though also ECU can be enrolled program.In like manner, also can understand, fuel control unit (for example from the combustion pipeline a kind of variable choke coil being set) can be set independently in leading to the oil supply pipeline of motor so that change engine oil according to disturbing signal.
Fig. 3 simply illustrates the another kind of method of disturbing fuel delivery.Wherein, a random disturbing signal E (in prespecified range) is introduced the target fuel feeding value F that is suitable for any engine operating condition that is determined by engine map, rather than change fuel feeding value F continuously.Therefore, when running into identical engine operating condition, motor all can turn round under different a little speed/load situations owing to the result of disturbance.Though the rotating speed of engine turbine pressurized machine all can be invariable in any work cycle if when job requirement do not changed.But the rotation speed change of turbosupercharger between the different operating circulation will be enough to alleviate the high frequency fatigue of turbine blade.
Be appreciated that as the situation of the top embodiment of the invention of explanation at first, need not above-mentioned disturbing signal is directly introduced oil supply system, and disturbed value can be added in the program of ECU.For example, when determining the fuel oil value, can regulate the fuel feeding value of determining by engine fuel figure by disturbed value E, and obviously, required disturbed value E not random at every turn, but will follow the work cycle of programming in advance.
People can understand that also above-mentioned two embodiments of the present invention can be incorporated in a kind of special purpose.Can pass through the first disturbance E when in other words, determining the fuel feeding value by fuel oil figure at every turn
1Change predetermined fuel oil value F and draw the fuel oil value Fm of change.Can apply the disturbing signal E that is changing then by the embodiment of the invention that illustrates at first
2Further change above-mentioned fuel oil value Fm, so the actual fuel oil value of supply engine is Fm-E
2(wherein E also be one can be on the occasion of or negative value, or can on the occasion of and negative value between the value that changes).
As further remodeling of the present invention, unnecessaryly under all engine operating conditions, all add above-mentioned disturbance, and just just add above-mentioned disturbance in the operating mode of predicting high frequency fatigue and will become particular problem, for example, can identify among the fuel oil figure zone that the operating mode of resonance may take place for operating mode or other expectation turbine blade corresponding to constant rotational speed/constant load.Then ECU or other nonshared control units are enrolled program, only implement the present invention in the above-mentioned this zone of fuel map.
But work as persons skilled in the art and will be readily understood that other possible remodeling of the present invention.
